4Application filed October 9, 1926.' Serial No. 140,590.

This invention relates to improvements in scythes, and it has moreparticular reference tofnovel Vmeans 'for connecting the blade to thesnathe ina manner to permit the bladevto be rotated around the snathe orto be ad'- justed angularly with respect to the same in order to makeconvenient the handling the scythe. l

The present invention is directed to an improvement upon Patent No.1,247,461 grant-r ln the patent referred to, a socket is providedincluding a cap to fit upon the end oi the snathe, this cap being formedwith a `toothed projection having a retaining. bolt associatedtherewith.

' The blade has a special heel constructionl which cooperates with saidtoothed part and it is provided with an elongated slot through which theclamping bolt extendsv and further provided with ,teeth adapted to belocked upon the 'first named teeth.

The socket is of split form and a clamping bolt is associated therewithfor per- Vmitting it to `be rotated about the snathe and clamped in anydesired position.

The present structure has been designed to improve upon the patentedstructure Yby re-4 arranging the cooperating retaining teeth,`

by providing a separate pivotal. connection between the blade and thesocket member, and to provide more eliicient clamping means for thesocket.

The speciiic details forming the'alleged improvement will. become morereadily apparent from the following descriptiony and drawings. f

ln the drawings forming a part ofthis application and in which likenumerals are employed to designate like Vparts throughout the same YFigure 1 is a rear elevational View of the complete structure.

Fig. 2 is an elevational view taken at approximate right angles andlooking at the end of the clamping means and blade, etc.

Fig. 3 is a detail elevationof the socket member, and y 'Fig dis adetail view of the blade retaining means.

In the drawing, Y designates the snathe, which has an upper thereference character 1 y tapered end fitting snugly intothe cap pori tion2 of the improved socket member. De-

pending from one side of this cap is a trans-v ing means 5. y

versely'curved apron 3, which isprovided at its lower end withoutstanding apertured ears 4. rIhe screw threaded ends of a pair ofvretaining bolts 5 extend through the ears 'and these bolts kare carriedOna U-shaped retaining strap. 6 having a central outwardly7 pressedportion 7 fitting overv adepending linger `Sx'mtherear half ot' thecap2. Y

' This 'serves'to hold the cap member in place and to permit it to beturned around the snathe to any desired position. Formed between theears von the lower .portion or' the apron 3 is a gear segment v9, and atthe center of this is a hole 101forpassage of a bolt 11.

`As shown in F ig. 2,a polygonal socket is formed in the inner side otthe gearsegment as shown and the head of the bolt is -located A' inthis` socket as indicated at 12. Y

'Extending upwardly ffroni the gear segment'V is a reinforcing-rib 13connected with a circular head 14 havinga correspondingly shaped socketor recess 15 formed therein.

. l The blade is represented by .the reference character 16 and the'same includes a special heel formation indicated at 17. On the innerface of this is a thickened portion 18 terminating at'its bottom in agear sector 19 cooperating with the lgear* segment 9. This vportion 19is .provided with an elongated arcuate slot 2O for registry with thebolthole 10 and the aforesaid bolt extends through this and carries aretaining nut 21 as shown in Fig.V 2. At the upper end of the'part 18-is a n circular projection 22 which lits into the .re

cess .15'.

A bolt 23 has head resting upon a seat i 2' and. has its shank`extendingY through Vopenings .in the head 14 and projection 22.

The clamping nut 25 thereonv is arranged in a depression 26 formed inthe outerside. The reference character 26 in Fig. l represents a beveledsurface and the referencecharacter 27 represents a'reinforcing rib whichis cut i away as at 28 to accommodate the adjacent `rounded periphery ofthe special head 14.

Withthe arrangement specified, it will be seen thata positive pivotalconnection is provided by the means 14, 22, and bolt23. Thus,

by simply loosening the nut 21 on the bolt 11,

the gear teeth 9 and19 maybe ratcheted over each other to permit theangularity of the blade being varied with respect to the snathe.Independent rotary adjustment of the socket member is permitted bytheaforesaid clampvFrom theV description and drawing, it will Y be seenthat the improvement is-characterizedby exceptional strength, simplicityof construction, inexpensiveness of man'u'facture, and efficiency inoperation and use. It is believed that by considering the description inconnection with the drawings, a clear uiiderstanding of the inventionwill be had'.

Therefore, a more lengthy description is thought unnecessary.

`,Haviiig thus described my invention, what .I claim as new is Y i l. Ina structure of the class described, ar

socket member including a cap, adapted to be fitted upon the end of asnathe,a head proj-V jectiiig abovek the cap and includingl a circularrecess, a blade having a lateral proJection ttingrotatably into saidrecess', a bolt passing .through said head, projection and blade, agea-r segment carried by the socket member, a gear sector carried by theblade and cooperable with the gear segment, and a vclainping above thecap, a inger dependingv from the rear half of the cap, a retaining strapcoopera'ble with said iinger, and bolts carried by said strap andext-ending thru the apertures in said ears."

In testimony whereof a'fix my signature.
